"Another style'of safety razor whicnenjcy fa wide popularity isthat known as the Ever-Ready razor EvereReady razor 'difiers-iro'm'the Gillette razor most ir'nnortantlyf in: the fact that it is specifically designed to employ a' bladei substantially sat unflexed condition.

The holder comprises a han-- die! and a head 2, the latter being made up of two separable elements, namely a guard 3 of generally rectangular outline and a cap4 adapted to overlie and cover the major portion of the The cap and guard are transversely guard. I curved and the longitudinal edgesaof the cap lie inwardly'oi the corresponding edges of'the guard. A screw-threaded stud '5, is secured tothe concave face of the. cap and is adapted: to ireely pass through a centrally disposed opening in the f guard and screwinto asocket I a provided in an end ofthe handle 1.

The slot is located below the point at which the stud joins the cap and, as best shown in Fig. 3, its l'ongi- 'tudinal walls slopedownwardly fromthe outer toward the inner face of the cap. v

The size of the slot is such as to allowa blade n of the semi-rigid, single-edge type'to be illtroduced therein with, itscutting edge extending down between the cap and the guard when the latter parts are inreleased position.
